Question

我需要一个针对此xpath查询的jackrabbit sql 2等效查询

xpath = "/jcr:root//institutes/institute[*]/(@title | @overallScore)"

我已经为sql2做了这个我可以通过使用ISCHILDNODE（）约束

获得'/IN/institues/institute'

但我希望以这种方式返回所有学院'/%/institutes/institute'。如果我能通过加入实现这一点，请告诉我完整的声明

Currenlty我正在使用此查询但没有成功

参考：reference link

sql2 = "SELECT institute.title, institute.overallScore FROM [nt:unstructured] AS country "
            + "INNER JOIN [nt:unstructured] AS institutes ON ISCHILDNODE(institutes, country) "
            + "INNER JOIN [nt:unstructured] AS institute ON ISCHILDNODE(institute, institutes) "
            + "WHERE NAME(institutes) = 'institutes' ORDER BY institute.overallScore DESC";

我还发现PATH（）之类没有在jackrabbit中实现

Answer 1

我自己没有测试过，我不确定它是否有效，但这个查询应该有效：

select b.[jcr:path] as [jcr:path], 
       b.[title] as [title], 
       b.[overallScore] as [overallScore] 
from [nt:base] as a 
inner join [nt:base] as b on ischildnode(b, a) 
where name(a) = 'institutes' 
and name(b) = 'institute'
